UNIX is the operating system of choice for scientists, programmers, and other such professionals because of the following benefits:

The complexity of make a custom operating system depends on the knowledge of the developer. If you intend to start a operating system from the scratch this could be a enourmous job and take some years to have a very simple and stable version. However it is possible to customize the open versions of existing operating system as Linux. On the internet you could find out that are many others versions of Linux that are frequently updated.
API
The operating system is immaterial. It is the languages used that are important. If you are targeting a specific platform then it obviously makes sense to develop upon that platform, but for cross-platform programming it really makes no difference what operating system you use.

Generally, anything written in java will transfer over to another operating system.

An operating system (OS) is an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of a computer, that acts as a host for computing applications run on the machine. As a host, one of the purposes of an operating system is to handle the resource allocation and access protection of the hardware. This relieves the application programmers from having to manage these details.
The operating system Linus Torvalds created and now expanded and improved by others is called Linux. It is frequently and incorrectly referred to as "GNU/Linux." On this operating system a massive range of system distributions were built, including Ubuntu, Android, Red Hat, Fedora, and SuSE.
Basic Machine, in computer parlance, means a computer without its operating system. Modern operating systems evolved through various stages, from elementary to the present day complex, highly sensitive real-time systems. In the very first stage of computing there was nothing like an Operating System at all. Programs were fed to the computer system directly using machine language by the programmers without any system software support. This approach is termed the "Bare Machine" approach in the development of operating systems.
